† Appearances (Goals).
His career started at AC Sparta Prague's youth academy which is known to have produced some of the Czech Republic's best footballing talent over the years. Rajnoch himself played with prominent Czech talents Tomáš Hübschman and Tomáš Jun in the youth teams. However he never made an appearance for the senior team. After spells at Bohemians Praha and 1. FC Slovácko he joined Czech Gambrinus liga outfit FK Mladá Boleslav in September 2006. Here he quickly established himself as a key player and became an integral part of the team, playing an important role in their UEFA Cup campaign wins against Olympique Marseille and Palermo. In the 2007–08 season, he was made captain and emerged as a firm fan favorite. Despite interest from Italy he decided to stay on at Mladá Boleslav to try and help the team win the title.
Switch to Germany
On 7 January 2009 Rajnoch made a loan move to German side FC Energie Cottbus where he played out the rest of the season making 10 appearances in the Bundesliga. However Cottbus could not avoid relegation and Rajnoch returned to Boleslav.
Despite interest from both Sparta Prague and Slavia Prague he moved to the Turkish Süper Lig outfit MKE Ankaragücü in 2010 on a three and a half year contract. He scored an own goal against Galatasaray on 2 October 2011 which became Galatasaray's 3000th goal in league history. So he somehow booked a place in Galatasaray history.
He plays as a defender or sometimes as a defensive midfielder. Although a strong defensive player, he has an eye for goal with a good shot and powerful presence in the air.
Rajnoch has played for the Czech Republic national football team. He was given his international debut on 20 August 2008 in a friendly against England at Wembley Stadium where he came on as a substitute for Radoslav Kováč in the 76th minute. The game ended in a 2–2 draw.
